HAIR-PIN.

Application filed May 28, 1912,

To all whom it may concern:

Be it known that I, CHARLns H. DnMPsnY, a citizen of the United States, residing at l'l'ecla, in the county of Hooker, State of Nebraska, have invented certain new and useful Improvements in Hair-Pins; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it-appertains to make and use the same.

This invention relates to hair pins and has for its object to provide a hair pin which may be securely held in position by oppositely directed pivoted fingers.

Another object is to provide a hair pin of this character having the usual form of legs projecting from a cylindrical head within which the securing fingers may be drawn during the operation of inserting the pin and properly positioning the same in the hair, after which the securing fingers may be forced outwardly through the opposite sides of the head and secured in such position to prevent the hair pin from working out of place.

With the above objects in view the invention consists of certain novel details of con struction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may 3e made in the minor details of construction within the scope of the appended claim.

In the accompanying drawing forming part of this specification :Figure l is a perspective view of the device with the securing fingers drawn into the head of the pin. Fig. 2 is a longitudinal sectional view through the device with the securing fingers positioned within the head. Fig. 8 is a similar view with the securing fingers in their outer position, projecting from opposite sides of the head. Fig. 4 is a detail view of the securing fingers and operating means therefor removed from the head.

Referring now to the drawing in which like characters of reference designate similar parts, 10 designates the legs which may be of the usual form or any form desired and are screwed at their opposite ends into the closed head 11 which is preferably of cylindrical form and has openings 12 at opposite points near the end 13 of said head to which the legs 10 are connected. The oppo- Specification of Letters Patent.

Serial No. 700,212. Renewed October 5, 1914. Serial No. 865,195.

site end 1 1 of the head 11 is provided with a threaded central opening 15 through which the rod 16 is adapted to move freely, said rod having threads 17 adjacent its opposite ends for engagement with the threads of the opening 15 to retain the rod in either position, as will be clearly understood.

Upon the end of the rod 16 within the head 11 is the enlarged member 18 which is preferably swiveled upon said rod and has the inner ends of the securing fingers 19 freely secured thereto at opposite points, said fingers 19 being extended through the openings 12 in the head 11 and adapted to be forced outwardly through said openings. The opposite end of the rod 16 is provided with the cap 20 by means of which the rod may be readily moved inwardly and outwardly to draw the securing fingers 19 into the head 11 or force the same outwardly through the openingsl2. When the securing fingers 19 are in their outward position and the rod 16 within the head 11, the cap 20 rests against the end 14 of the said head.

In use, the cap 20 is grasped and given a slight turn to disengage the threaded portion 17 of the rod 16 from the threads of the opening 15 and the rod 16 drawn outwardly to position the securing fingers 19 within the head. The legs 10 are then properly engaged with the hair and the pin forced into proper position, after which the rod 16 is again forced inwardly to compel the securing fingers 19 to move outwardly through the openings 12 and in opposite directions from the head 11 and transversely thereof. After the fingers 19 assume their outward position, the rod 16 is again given a slight turn but in the opposite direction to cause the threaded portion thereof adjacent the cap 20 to interlock with the threaded opening 16 and thus lock the rod 16 in the head 11 and the securing fingers 19 in their outward position. To remove the pin, it is simply necessary to reverse the above described operations, as will be clearly understood.

From the foregoing it will be apparent that I have provided a hair pin of improved construction and which may be readily forced into position and securely held in place and which may also be readily removed when desired.

It will of course be understood that minor changes in the details of construction may each end adapted to selectively engage the threads of the said opening, a swiveled member on the lower end of the rod, and resilient fingers pivoted to the member and 15 having their lower extremities engaged in the openings in the side Wall of the head.

In testimony whereof, I affix my signature, in presence of two Witnesses.
